Abstract
A dielectric fluid includes a first liquid having first dielectric constant and conductivity values. The dielectric fluid also includes a second liquid having second dielectric constant and conductivity values. The first dielectric constant value is greater than the second dielectric constant value and the second electrical conductivity value is less than the first electrical conductivity value. The first and second liquids form an immiscible mixture that has third dielectric constant and conductivity values between the first and second dielectric constant values and the first and second electrical conductivity values, respectively. The first liquid forms a high conductivity phase representative of the first conductivity value, and the second liquid forms a low conductivity phase representative of the second conductivity value. The low conductivity phase is continuous the high conductivity phase is a plurality of droplets non-homogeneously dispersed within, and separated by, the continuous low conductivity phase.
